Newer Version Available

A new version of this board is available. It fixes problems with the reset signal and power jack.

You can easily identify the board version by the location of the 100 ohm resistor.

Old Info:

This is the little test board shown here:

http://www.pjrc.com/store/display_ili9341.html

Parts used on the board are:

    LM7805 voltage regulator        Digikey LM7805ACT-ND
    B130 Schottky diode             Digikey B130-FDICT-ND
    140 mA PTC fuse                 Digikey 507-1495-1-ND
    100 ohm 1/4 watt resistor       Digikey 100XBK-ND
    DC power jack                   Mouser 163-7620E-E
    1uF 0805 capacitor              Digikey 1276-1066-1-ND

Component Placement

This PCB has the display RST signals connected to pin 8, not 3.3V. This special step is needed to make it work.

When using the RadioHead library, edit the Arduino sketch examples to specify pins 15 and 16. For example:

    // Singleton instance of the radio driver
    RH_RF69 rf69(15, 16);

Discussion and more documentation for this adaptor can be found here:

A newer version of this PCB was designed, with the ability to disable the SPI SCK signal (possibly causing RF interference on the RFM69 module), but so far it is untested.
